Boot-tree



A. J. WISNER, OF HOMER, NEW YORK.

BOOT-TREE.

Specicaton of Letters Patent '.o. 20,9114, dated July 13, 1858.

To all whom t may concern.'

Be it known that I, A. J. IVISNER, of Homer, in the county of Courtland and State of New York, have invented a new and useful Improvement in Boot-Trees; and

I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure 1 is a longitudinal section of the boot tree constructed with my improvement. Fig. 2 is a face view of interior of shin piece; showing manner of attaching the nut.

The object of my invention is to so construct the tree that either the upper or lower portion of the same may be forced to any desired position and kept there as long as necessary, and without reference to the movement of the other part, and also to provide the means of preventing the stretching of the boot from removing the crimp. The nature of the invention consisting in a peculiar combination of devices hereinafter to be set forth.

In the drawing A is the calf portion of the tree, and B the shin piece thereof; the stretching being effected by the front movement of this latter portion, side-plates for guides being attached to the calf piece.

The foot C has a hinged sole D, capable of being forced downward by the longitudinal movement of the shin shaft E. A screw thread a passing through the yoke piece b, secured to the shin piece, and thus giving the said shaft its forward movement.

Connected with the yoke o is the screw F working in the back plate 0. The turning of this screw gives motion to the upper extremity of the shin piece.

Passing down the front of the calf piece and held at top by plate d, and at bottom in the bearing e is a shaft G. On its lower end is a bevel wheel l/V, meshing with a similar wheel IV upon screw -shaft H, attached to calf piece as shown in the drawing. The screw H passes through a nut I in the shin piece, held loosely by arms z' behind plate f, so as not to join when the shin piece moves. The turning of shaft G causes the withdrawing of screw H from its nut and the consequent forcing out of the lower end of shin piece.

By this construction either of the ends of the shin piece may be forced out and retained in the desired position without reference to the movement of the other end. Moreover, the danger of removing the crimp by the treeing operation is altogether obviated by the means furnished to maintain the proper elevation of the instep; consisting of thefshin shaft and hinged sole.

By the construction here described all parts of the boot are forced into the desired form, and the stretching of one part is not allowed to draw in any other part.

Having described my invention and the operation thereof, I claim- The combination of shaft G, bevel wheels W VV, screw H, nut I, screw F and yoke ZJ, with the shin shaft E and hinged sole D, the whole constructed and arranged for oint operation substantially as, and for the purpose set fort-h.

In testimony wherof, I have hereunto signed my name before two subscribing witnesses.
